The ExpertTM is the new generation electroencephalograph
that allows to widen the sphere of use of electroencephalography
in clinical practice.

The ExpertTM uses digital telemetry and
allows continuous 24-hour's recording. The EEG signal is transmitted
digitally to the registration device via radio frequencies or mobile
(GSM, CDMA, NMT and other standards) and dedicated phone lines.
The wireless system significantly simplifies the EEG examinations
during scientific research and in clinical use.

The ExpertTM is much less sensitive to
the pulse and systematic noise than any stationary EEGs, it is portable
and light that further eases its use and increases quality of analysis.
There are the following main advantages of ExpertTM as compared
to traditional systems:

Full electric safety of III CF type class due to use of batteries
and telemetry;

Better quality of EEG registration;

Insensitivity to a number of physical and physiological artifacts
that eases the work of staff and increases the capacity of the
system;

Routine EEG examination may be extended to needed scope in any
time;

The system can be enhanced by:

adding PCs to carry out online EEG registration and transmission;

adding EEG amplifiers to widen the capacity of the system
to three patients per one PC;

corrections of the EEG amplifier characteristics by reprogramming
of the built-in processor;

increasing the range of the telemetry by adding supplementary
antennas.

The built-in processor allows to carry out digitization,
filtration, compression and coding of the signal directly in the
EEG-amplifier. This allows to transmit digital EEGs wirelessly with
no interferences, including 50Hz background noise. The low radiation
and energy consumption of the EEG amplifier allows ExpertTM
to work for 24 hours without recharging the batteries. The high
input resistance allows using the standard EEG gel for 24-hour EEG
recording and reducing the number of physiological artifacts.

The built-in system of autocalibration allows
testing the EEG amplifier, radio channel and software simultaneously.
The unit has the low battery indicator. The ExpertTM is user-friendly;
it is turned on by push of one button and does not provide the patient
with control over the system.

The basic features of the equipment:

Control of sensitivity, bandwidth and scan rate;

refiltering of recorded EEGs;

trigger and rhytmical photo- and audiostimulation;

various changing combinations of channels and electrodes (monopolar,
bipolar and multipolar);

possibility to review recorded EEG in any combinations of channels
and electrodes at the user's option;

possibility to magnify selected channels parallel to other channels
in two windows;

adjustment of "paper size";

automatic or manual measuring of the parameters of selected
sections of EEGs in a special window;

automatic scrolling of EEGs with mapping on standard or corrected
frequency ranges;

ranging of the selected interval of the curve and comparing
of symmetrical channels;
